The rapid depletion of conventional fossil fuels from the earth, and ever-growing demands for power generations, force the entire industrial world to search for new fuels that can replace the conventional fossil fuels. Also, an abundance amount of greenhouse gas emissions into the atmosphere like carbon dioxide, oxide of nitrogen, etc., are responsible for a consistent increase in environmental temperature, leading us to explore a reliable and efficient alternative fuel. One example of this alternative fuel is bio-derived synthetic gas (Syngas), produced by biomass gasification process. However, lower heat content and incombustible species content in the fuel makes Syngas challenging for gas turbines. In the proposed work, several experiments were carried out with fossil fuels (A.T.F., Diesel, etc.) for initial characterization of the micro gas turbine to investigate the performances such as TIT, the mass flow rate of fuel, and air, turbine output power/thrust. A thermodynamic and energy equilibrium analysis has been carried out for different alternative fuels (S.G., P.G., B.F.G.) to achieve the same TIT and power output for micro gas turbines. It is observed from the analysis that Syngas is the most promising fuel compared to other fuels for use in the gas turbine. For the same amount of fuel supply, only 7% power derating is dictated. That derating can be further reduced by an additional amount of fuel supply and by little modification of the gas turbine combustor. A simple five elements (4 PSR’s-Perfectly stirred reactor and 1 PFR – Plug flow reactor) gas turbine reactor network is proposed in the current analysis for the Syngas combustion in the gas turbine engine. The reactor network analysis presents a mechanism for different regions of a gas turbine combustor. In the reactor network, four PSR reactors serves as the different regions of the gas turbine combustor, i.e., Primary, Secondary, Dilution and Recirculation zones and the post flame zone simulated by PFR. The proposed reactor network predicts turbine inlet temperature in the range of overall equivalence ratios of 0.23-0.43. From the network analysis it has been well understood that, the energy and mass flow distributions required in a gas turbine combustor when fuelled with Syngas.
